Small "Coronal Cloud" event where material is visible above the limb without much attachment back to the disk. A small amount of material can be seen returning to the disk in the form of coronal rain.

Could be a micro flare. There is also a large eruption north from the flaring region, which may be related to the flare (happens at the same time) and/or be driven by interacting small-scale magnetic elements.

Opposite-polarity magnetic features are cancelling close to penumbra, causing a large-scale brightening and several eruptions.

Small eruption in AR 12795. Based on HMI magnetograms, the eruption could be driven by interaction of small-scale opposite polarity magnetic elements at the edges of penumbra.

A prominence above AR 12792. The slit is crossing the event. There is a bubble-like structure forming, but it could also be just loops extending above the AR.

A weak flare (A or B level) is observed in AR 12795. The brightenings have dotted regions in the north and a narrow ribbon in the south. The IRIS slit crosses both regions.

A small B-class flare in AR 12791 erupts just to the right of the spectrograph slit, resulting in plasma flows along the flare loops in the coronal and a complex pair of flare ribbons make a rough ")(" shape near the flare origin. As the flare evolves, the left-hand member of these ribbons curls back around on itself to make nearly a complete circle enclosing a supergranule. A series of brightening events occur inside the ribbon until the entire encircled supergranule is filled in.

AR 12786 has a large sunspot with a moderate activity. No flare or eruption occurred.\nIn the complex region of the penumbrae, we can see oscillating brightening features in 1330 and 1400 passbands. These feature are not seen in 2796 passband. They correspond to spicular motions, which may be heated at the top of spicules.

AR 12790 has a small sunspot. This region had an M-class flare at the east limb, and was expected to have more large flares. However, no flare more than C-class took place in the following two weeks.\nThis is a small activity in this AR. First, a small twisting ejecta can be seen in the bottom-right area of the FOV with a related brightening close to the sunspot. The brightening shows both blueshift and redshift components, and it can be associated with the ejecta. After a while, a larger ejecta is observed with a twisting motion and a two-ribbon brightening.
